Question

A scientist is studying a population of elephants contained in an animal preserve. Which of the following must be true if the size of the population is increasing?

A. The birth rate has dropped to zero
B. The birth rate is equal to the death rate.
C. The death rate is greater than the birth rate.
D. The birth rate has become greater than the death rate.

Answer 1

If the size of the elephant population is increasing, it means that the birth rate is greater than the death rate.

Step-by-step explanation:

The birth rate is the number of births within a population during a specific time period, while the death rate is the number of deaths within a population during a specific time period. If the size of the elephant population is increasing, it means that the birth rate is greater than the death rate. Therefore, the correct answer is option D - The birth rate has become greater than the death rate.
